AMD Ryzen AI Embedded P185 vs Intel Core Ultra 9 285 Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep in the head-to-head benchmark set. The Intel Core Ultra 9 285 wins all 11 recorded comparisons against the AMD Ryzen AI Embedded P185, but the margins vary widely by workload. The narrowest gap appears in integer math, where Intel leads by 28.5% (164,869 vs. 117,832). Single-thread performance is closer still in relative terms, with the Intel part scoring 4,881 against 3,977 for the AMD chip, a lead of 18.5%. These two results frame the overall comparison: the Intel processor is faster across the board, but the scale of its advantage depends heavily on the instruction mix.

The largest deltas appear in math-heavy and encryption workloads. The Intel Core Ultra 9 285 delivers 194,988 in floating-point math, which is 63.8% ahead of the Ryzen AI Embedded P185's 70,587. Data encryption shows an even bigger gap: Intel scores 46,949 versus 19,612, a 58.2% deficit for the AMD part. Prime number finding is the most lopsided test in the set, with Intel at 459 against 129, a 71.9% advantage. These three results indicate that the Intel processor has a substantial throughput advantage when the workload is dominated by dense mathematical operations.

Multithreaded and physics tests follow the same pattern. The Intel Core Ultra 9 285 reaches 56,602 in PassMark multithread, while the AMD Ryzen AI Embedded P185 manages 31,817, leaving the AMD chip 43.8% behind. Physics scoring shows Intel at 3,598 versus 1,772, a 50.8% lead. Data compression is also strongly in Intel's favor, with 602,121 against 374,429, a 37.8% gap. Extended instruction performance favors Intel by 41.5% (45,357 vs. 26,544), and random string sorting favors Intel by 44.9% (73,651 vs. 40,557).

The average benchmark score in the database confirms the overall hierarchy. The Intel Core Ultra 9 285 sits at 75,488 average, while the AMD Ryzen AI Embedded P185 sits at 62,839. That places Intel in the 95th percentile of all CPUs tracked, with the AMD part in the 93rd percentile. Despite the one-sided head-to-head, the AMD chip's nearest rivals include the Intel Core Ultra 7 255HX at 62,738 (0.2% behind) and the AMD Ryzen AI 9 PRO 465 at 62,498 (0.5% behind), meaning the P185 is competitive within its own performance tier even though it falls well short of the Ultra 9 285.

Where Each One Wins

The benchmark data does not record a single test where the AMD Ryzen AI Embedded P185 beats the Intel Core Ultra 9 285. Every measured workload, from single-thread to multithread, from integer to floating-point, from compression to encryption, lands in Intel's column. The closest contest is integer math, where the AMD chip trails by 28.5%, and single-thread performance, where it trails by 18.5%. Those are still decisive margins, but they are the two areas where the AMD processor comes closest to parity.

The Intel Core Ultra 9 285 wins decisively in every throughput-oriented category. Its multithread score of 56,602 is 43.8% above the AMD part, and its physics score of 3,598 is 50.8% higher. For workloads that rely on encryption, extended instructions, or floating-point math, the Intel processor is the clear choice based on the recorded deltas of 58.2%, 41.5%, and 63.8% respectively. Data compression and random string sorting also favor Intel by 37.8% and 44.9%, which reinforces the pattern of broad, consistent dominance.

The AMD Ryzen AI Embedded P185 does not win any recorded benchmark, but its profile still matters for positioning. With a 12-core, 24-thread configuration and a 28 W TDP, it occupies a different power envelope than the 65 W Intel part. The data does not show a single workload where the AMD chip's lower power draw translates into a performance win, but the average benchmark score of 62,839 places it just 0.4% below the Intel Core i7-13790F and 0.5% below the Intel Core Ultra 7 265HX in the nearest-rival list. That places the P185 firmly in the upper mid-range of desktop and mobile processors, even if it cannot challenge the Ultra 9 285.

Specification Differences

The two processors differ substantially in core configuration. The AMD Ryzen AI Embedded P185 uses 12 cores and 24 threads, while the Intel Core Ultra 9 285 uses 24 cores and 24 threads. The Intel part has no hyperthreading advantage, but it doubles the physical core count. Base clocks favor Intel at 2.50 GHz versus 2.00 GHz, and boost clocks favor Intel at 5.60 GHz versus 5.10 GHz. The TDP figures are far apart: the AMD chip is rated at 28 W, while the Intel chip is rated at 65 W.

Cache hierarchies are also different. The AMD Ryzen AI Embedded P185 provides 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3 cache. The Intel Core Ultra 9 285 provides 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. Memory support overlaps on DDR5, but the AMD part also lists LPDDR5X. Measured memory bandwidth favors Intel at 102.4 GB/s versus 89.6 GB/s. Both processors support ECC memory.

Platform support differs completely. The AMD Ryzen AI Embedded P185 uses AMD Socket FP8 and is classified as a mobile part, while the Intel Core Ultra 9 285 uses Intel Socket 1851 and is classified as a desktop part. PCIe generation and lane counts differ: AMD provides Gen 4 with 16 CPU lanes, while Intel provides Gen 5 with 20 CPU lanes. Integrated graphics also differ, with the AMD part using Radeon 890M and the Intel part using Arc Xe-LPG Graphics 64EU. The Intel processor has a launch MSRP of $579. The AMD processor is unlocked in neither case; both have locked multipliers.

Architecture Differences

The AMD Ryzen AI Embedded P185 is built on Gorgon Point, a codename within the Ryzen AI Embedded generation that uses Zen 5 and Zen 5c cores. The manufacturing process is 4 nm at TSMC, with a die size of 233 mm². The Intel Core Ultra 9 285 uses Arrow Lake-S architecture from the Core Ultra Series 2 generation, built on a 3 nm process at TSMC, with a die size of 243 mm² and 17,800 million transistors. The Intel part is the only one of the two with a recorded transistor count in the database.

Core design philosophy differs between the two. The AMD chip pairs 12 cores with 24 threads, indicating simultaneous multithreading on each core. The Intel chip pairs 24 cores with 24 threads, meaning each core operates without SMT. The L3 cache allocation is also distinct: the AMD part has 16 MB total, while the Intel part has 36 MB shared. L1 and L2 per-core allocations are larger on the Intel side at 192 KB and 3 MB respectively, versus 80 KB and 1 MB on the AMD side.

Process node and release timing also separate the two. The Intel Core Ultra 9 285 has a release date of 2024-12-31 and uses a 3 nm node, while the AMD Ryzen AI Embedded P185 has a release date of 2026-02-28 and uses a 4 nm node. Both are produced at TSMC, and both are marked as active in production. The Intel part carries the part number SRQD4, while the AMD part's part number is listed as unknown.

The Verdict

The data points to a clear performance hierarchy. The Intel Core Ultra 9 285 wins every recorded benchmark against the AMD Ryzen AI Embedded P185, with deltas ranging from 18.5% in single-thread to 71.9% in prime number finding. Its average benchmark score of 75,488 and 95th percentile ranking place it among the fastest CPUs in the database. The AMD chip, with an average of 62,839 and a 93rd percentile ranking, is a strong performer in its own tier, but it does not challenge the Intel part in any measured workload.

Use-case separation follows the power and platform classification. The AMD Ryzen AI Embedded P185 is a mobile processor with a 28 W TDP, 12 cores, 24 threads, and support for both DDR5 and LPDDR5X. Its lower power envelope and mobile socket make it suitable for embedded and portable systems, though the recorded benchmarks show it trailing the Intel desktop part by 28.5% to 71.9% depending on the test. The Intel Core Ultra 9 285 is a desktop processor with a 65 W TDP, 24 cores, 24 threads, PCIe Gen 5 with 20 lanes, and a launch MSRP of $579. Its higher power budget and larger core count deliver the multithreaded and math-oriented wins recorded in the head-to-head set.

The verdict from the recorded data is straightforward: the Intel Core Ultra 9 285 is the faster processor in every benchmark category measured, and the AMD Ryzen AI Embedded P185 is the lower-power mobile alternative that cannot match it in raw performance. The AMD chip's closest recorded rivals are the Intel Core Ultra 7 255HX, Intel Core Ultra 7 265HX, Intel Core i7-13790F, and AMD Ryzen AI 9 PRO 465, all within 0.5% of its average score. The Intel part's nearest rivals are server and workstation class chips such as the AMD EPYC 8224P and AMD Ryzen 7 PRO 9755X3D, which confirms its position in a higher performance bracket.
